The Committee recommended that the vigilance operations in respect of the National Malaria Eradication Programme should be the responsibility of the primary health centres at the block level. The Committee also recommended that vigilance operations such as monthly home visits should be implemented through basic health workers. One basic health worker per 10,000 population was recommended. These workers were envisaged as 'multipurpose workers' to look after additional duties of collection of vital statistics and family planning, in addition to malaria vigilance. The Family Planning Health Assistants were to supervise 3 to 4 of these basic health workers. At the district level, the general health services were to take responsibility for the maintainence phase.
